MACHINE FOR COILING WIRE RODS.

SPECIFICATION forming part of Letters Patent No. 458,572, datedSeptember 1, 1891.

Application filed November 15, 1889. Serial No. 330,494. (No model.)

To aZZ whom it may concern:

Be it known that I, BURTON H. GEDG-E, a citizen of the United States,and a resident of the city of Anderson, in the county of Madison andState of Indiana, have invented certain new and useful Improvements inMachines for Coiling Rods, of which the fol1owing is a specification.

The several features of my invention and the advantages arising fromtheir use, conjointly or otherwise, will be apparent from the followingdescription.

In the accompanying drawings, forming part of this specification, Figure1 is an elevation of the device. Fig. 2 is a central vertical section ofthe lower part of the device. Fig. 3 is a top view of the upper part ofthe device. Fig. 4: is a top view of the lower part of the device, theupper part being removed.

The shaft A is suspended in bearings a a, attached to suitable supports.At its upper end it has the beveled friction-gear A. The drum B iscentered on the shaft A. It is cylindrical in shape and its lowerportion is preferably contracted, forming an arched space under theshoulder b. In the lower portion of the drum B a suitable number ofslots 1) are out. Each hookD has two parts made in one-viz., curvedportion or finger d and the straight portion or arm d, which projectsfrom the end of the finger d at an angle. Each hook D is pivoted at theangle d in one of the slots 12'. In place of one of the movable hooks D,the hook C is rigidly attached to the drum B, as indicated in Fig. 2.From each of the arms d a connecting-rod e extends to the movable collarE, surrounding the shaft A. The collar E is united to the collar F byany suitable means, preferably rods f. The collar F is placed far enoughup on the shaft A to be at all times above the drum B. Between the topof the drum B and the collar E on the shaft A an expandingspring S isplaced.

In Figs. 1 and 4 a brace \V is shown as a means of support to thehelical guide G, which curves around and downwardly about the drum Binto the space formed by the hooks D. The pipe H is the conduit throughwhich the wire or rod passes from the mill to the coil ing-machine.

Returning now to the collar F, we find it surrounded by an outlyingcollar I. These two collars are united by afeather-and-groove joint,which permits the inner collar to rotate with the shaft A withoutimparting its motion to the collar I. The connecting-rods J extend fromthe collarI to the lever K, which latter is attached to the cam L andhas for its fulcrum the pivot of the said cam. The cam L is pivoted tothe bearing L. It is a circle with a flattened face Z, which bearsagainst the friction wheel M when the collar I is pushed down to itslowest limit. The beveled friction-gear M is feathered on thedrivingshaft N, and is held against the friction-wheel A by means of aspring 0, compressed between the wheel M and the stationary collar or.

The mode of operation of the device is as follows: Motion is imparted tothe shaft N, and through it to the shaft A, which causes the drum B andthe parts attached to it to rotate. Preferably this motion is veryrapid. A rod from the mill is fed to the machine through the conduit H.This rod impinges against the guide G, which directs it into the gutterformed by the hooks D, the guide also serving to prevent the rodspringing up and out of the hooks. The hooks D move so rapidly that thegutter formed by them is practically solid. The rod is fed to the coilervery rapidly, and it is necessary for the latter to turn at least asrapidly as the rod is fed to it, and preferably a little more rapidly.As the rod is fed to the coiler it is carried around and around by thehooks, slipping a little until a sufficient number of coils havecollected to make it bind on the reel, when the coils are tightened,and,increasingin number, a bundle is formed. When the machine turnsfaster than the rod is fed to it, the tightening of the rod holds thedrum B back and causes the friction-wheel A to slip on thefriction-wheel M, thus preventing the stretching or breaking of the rod.When the bundle is com pleted, the handle of the lever K is depressedslightly. This movement forces the cam L against the friction-wheel M,and, moving it slightly away from the friction-wheel A permits the shaftA and its attachments to slow down and stop. The handle of the lever Kis'now still further depressed, with the effect of raising the collars Fand E and dropping This drops the coil R, which the hooks D.

remains hanging on the stationary hook C, from which it may be removedby tongs or other suitable means.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of the revolving shaft A, drum B, hooks D, havingcurved fingers d and arms d and pivoted to the drum B, connecting-rodse, collars E and F, rods f, and rod for raising and lowering collar F,substantially as and for the purposes specified.

2. The combination of the revolving shaft A, drum B, hooks D, havingcurved fingers (Z and arms (1 and pivoted to the drum B, connecting-rodse, collars E and F, spring, S, rods f, and rod for raising and loweringcollar F, substantially as and for the purposes specifled.

The combination of the revolving shaft A, drum B, hooks D, having curvedfingers (Z and arms d and pivoted to the drum B, connecting-rods e,collars E and E, spring S, rods f, collar I, rod J, and lever K,substantially as and for the purposes specified.

4c. The combination of the revolving shaft A, friction-gear A, drum B,hooks D, having curved fingers d and arms (1 and pivoted to the drum B,connecting-rods e, collars E and F, spring S, rods f, collar I, rod J,lever K, cam L, having face Z, shaft N, having collar n, friction-gearM, and spring 0, substantially as and for the purposes specified.
